In this project I take an Arduino Mini Pro
connect it to a custom made Etch A Sketch
panel and use it to control a Blacknose laser cutter
. The result is hours of crazy laser cutting fun, which we will be taking round most of the UK Maker Faires this year for JustAddSharks.co.uk
he Etch A Sketch has 2 knobs in the lower corners, one controls movement in the X axis and the other controls movement in the Y Axis. The laser cutter also has an X and a Y axis so each knob is mapped directly to the appropriate axis. The laser is only turned on while the axis are moving which prevents the laser from setting fire to the material it is cutting.
The control is all done using the Arduino Mini Pro which shows that small can also be powerful. The lack of processing speed to produce stepper motor pulses is compensated for using the hardware PWM modules in exactly the same ways as described in my previous instructable
We will be taking this whole project to the UK Maker Faire
at the end of April as well as numerous other UK Maker Faires this year so if you're lucky you can come and visit us and give it a try for yourself.
